Title: Transparent heat-insulating film and its manufacture
Inventor: HANSU YOOHIMU GUREEZERU
IPC: C03C17/36
Filed: 1983-03-28
Abstract: A transparent, heat-insulating coating, neutrally acting in transparency and external appearance, for transparent substrates, more particularly for insulating glass panes, is disclosed. The coating is formed from a bismuth oxide-silver-bismuth oxide multilayer system in which a more electronegative substance, i.e. a substance with a higher normal potential, is added to the bismuth oxide layers to avoid blackening under UV radiation. If manganese is used as the electronegative substance, its oxidation to higher valency states can be prevented by the addition of trivalent substances. The layers may be applied in a conventional way by diode-cathode atomization.

Title: Data input system for console display device
Inventor: SHIRAISHI HISASHI
IPC: G06F3/048
Filed: 1989-03-03
Abstract: PURPOSE:To omit the second keying against the detection of an error and to extremely improve the operability of a data input system by storing temporarily the latest input data applied to a computer system to display it again after the restoration and correcting partly the data to apply it to the computer system again. CONSTITUTION:An input data temporary memory means 4 stores temporarily the received latest input data when the data which gives an operating instruction of a computer system is displayed and applied again to the computer system. An input data restoring means 5 actuates a restoration key to restore the input data stored temporarily and displays it again. The input data restored by the means 5 and displayed is partly corrected and applied again into the computer system by an input data correction means 6. Thus an error of the latest input data can be corrected by restoring the applied latest input data via the restoration key. Therefore it is not required to perform the second keying for all input data when an error is detected. Then the operability is improved for a data input system.
